But Bo Jackson could do, like, anything on the diamond. And on the gridiron.

The SMR has his Donruss Rated Rookie card at $10 in MINT (9) and $25 in GEM-MT (10) condition.

For another thing, Maddux had just landed a spot in the Chicago Cubs rotation and was a year out from turning in his first big season — 18-8, 3.18 ERA, an All-Star selection for the 1988 Cubs club that played the first night games at Wrigley Field.

All told, he went deep 49 times in 1987 to set the rookie record that stood until Aaron Judge undid it in 2017. Along the way, Big Mac’s cards rose to the top of the hobby Hot List, and this Donruss Rated Rookie beauty trailed only McGwire’s 1985 Topps Team USA issue in value and popularity.
